Thank you for the news!. One important lesson we electronic
experimenters should draw from these FAQ is car batteries are not a
good choice for us, their specialty is delivering huge starting
currents, but they suffer a lot if discharged almost completely, even
with small currents.

=====================================
However car batteries can be used very effectively for amateur radio
operations by using them as a peak current provider in conjunction with
a modest (current wise) PSU.
A nominal 100 W RF SSB transmitter might need say 20 Amperes in the
peaks , but (even with audio processing) ,on transmit ,the average
current will hardly exceed 8 Amperes and taking into account a 50/50
tx/rx duration ratio , such a transmitter will happily operate for long
periods with a say 60Ah car battery and a 6 Amperes power supply unit.
And the battery will have a long life. Of course ,to be close to the
transceiver the battery will have to be of the sealed variety .

a certain g7 used to charge his batteries on night-rate electricity and

and that was in the mid 90's.

Above info is possibly NOT relevant . The topic is : Running amateur

Unless the night rate were substantially less than the day rate, inherent
losses in any energy conversion proly make this strategy a wash.
At 80% of the day rate, he was proly breaking even.

Don't know if the OP was from the UK, but UK night rates are of the
order of half the day rate (though you have to pay a higher day rate to
qualify!), but only for 7 hours. I do wonder if it would be possible
now to set up a battery/inverter/load sharing system sufficiently
cheaply to lower the cost of daytime use significantly. Probably
illegal though.
================================
Why would it be illegal storing energy ? I can't imagine that it is
illegal charging the batteries of a Golf buggy , at night tariff.
I am sure any golf club would do that to reduce their electricity bill.

BTW ,living in the UK myself ,night tariff indeed normally starts at
about 2300 hrs and finishes at 0600 hrs the following morning .
At our place switching happens with an electro-mechanical timer with a
spring mechanism such that following an outage the timer keeps running.
Eventually that spring has to be re-wound by the electricity supplier
,but that hasn't happened the past 15 years........so the timer at our
place now comes into operation around 2320 hrs ,but then of course also
day tariff starts about half an hour later at 0620 the following morning.
